概述：UISwipeGestureRecognizer滑动手势，继承于UIGestureRecognizer类。

手势的配置

/*滑动的方向*/
@property(nonatomic) UISwipeGestureRecognizerDirection direction; 
/*滑动的方向按位枚举*/
typedef NS_OPTIONS(NSUInteger, UISwipeGestureRecognizerDirection) {
     /*默认值，向右滑动*/
    UISwipeGestureRecognizerDirectionRight = 1 << 0,
     /*向左滑动*/
    UISwipeGestureRecognizerDirectionLeft  = 1 << 1,
    /*向上滑动*/
    UISwipeGestureRecognizerDirectionUp    = 1 << 2,
    /*向下滑动*/
    UISwipeGestureRecognizerDirectionDown  = 1 << 3
};

/*滑动的手指数*/
@property(nonatomic) NSUInteger                        numberOfTouchesRequired __TVOS_PROHIBITED;

案例：

 UISwipeGestureRecognizer* swipeDirection = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDirectionMethod:)];
/*设置滑动方向*/
 swipeDirection.direction = UISwipeGestureRecognizerDirectionRight;
 [self.view addGestureRecognizer:swipeDirection];

/*方法实现*/
- (void) swipeDirectionMethod:(UISwipeGestureRecognizer*) swipeDirection
{
     if(swipeDirection.direction == UISwipeGestureRecognizerDirectionRight)
     NSLog(@"向右滑动,%lu", swipeDirection.direction);
}

注意：如果要实现多个方向滑动，必须定义新的UISwipeGestureRecognizer对象，而不是用运算符“|”来表示，例如：

/*错误*/
UISwipeGestureRecognizer* swipeDirection = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDirectionMethod:)];
swipeDirection.direction = UISwipeGestureRecognizerDirectionRight|UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeDirection];

/*正确*/
UISwipeGestureRecognizer* swipeDirection_Right = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDirectionRightMethod:)];
UISwipeGestureRecognizer* swipeDirection_Left = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDirectionLeftMethod:)];
swipeDirection_Right.direction = UISwipeGestureRecognizerDirectionRight;
swipeDirection_Left.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer: swipeDirection_Right];
[self.view addGestureRecognizer: swipeDirection_Left];

/*方法实现*/
- (void) swipeDirectionRightMethod:(UISwipeGestureRecognizer *)swipe {
    NSLog(@"向右滑动");
}

- (void) swipeDirectionLeftMethod:(UISwipeGestureRecognizer *)swipe {
  NSLog(@"向左滑动");
}
